Abstract: A hydrogen production apparatus includes a first separation device that separates hydrogen from a first steel by-product gas and discharges a first mixed gas containing carbon monoxide and methane, a reforming device that generates the hydrogen and the carbon monoxide from the first mixed gas by using a reforming reaction, a heat supply device that generates heat energy using a second steel by-product gas as a combustion material and provides the heat energy to the reforming device, and a second separation device that individually separates the hydrogen and the carbon monoxide generated by the reforming device.

Abstract: A hydrogen production apparatus includes a first separation device that separates hydrogen from a steel by-product gas and discharges a first mixed gas containing carbon monoxide and methane, a pre-reforming device that receives the first mixed gas and a first water vapor, converts hydrocarbon into methane, and discharges a second mixed gas containing the methane, a mixed reforming device that receives the second mixed gas and a second water vapor and discharges a third mixed gas containing the hydrogen and the carbon monoxide, and a second separation device that individually separates the hydrogen and the carbon monoxide from the third mixed gas.
